Need Help with Profile Photo

[Tigres03]

Hi, I hope this is the right place to post this.

I've been trying to set my profile photo but none of my photos fit the size. I saw someone suggest uploading the photo on a website and get a link and it will bypass the size issue but when I did that Magistream denied it saying the website I used was a possible risk. Does anyone know what I can do or what site Magistream thinks is safe?

Thank you.
